 I have the exact configuration you have and I have not had any problems
 with the VGA display whatsover.......Perhaps you should seek a second
 opinion, tech wise, that is.  The Z-549 could be bad?

Actually, I have had three different service centers try and deal with
the problem and they all failed.  If you have the paradise version of the
z-549 board then you will not have the problem.  If you have the other
Z=549 you will have a problem.  I have had at least twenty different
boards in the machine and at least eight different 1492 monitors that
would not work.  Which Z-549 board do you own that works?  Does any
one else have the same set up that does work?

My Z-386-25 initially had the problem but replacing the 1492 fixed the
problem.

I have verified the problem on three other Z386-33's that I had access
to.

It was this problem which caused me to stop my service contracts with
Zenith.  There is a problem which is repeatable every single time and
yet no fix is/has been done.  As such I have started replacing my equipment
with non-zenith equipment from companies that take stuff back when there
is incompatibilities.

BTW, if I turn the monitor off and let it sit for about five minutes then
turn it on after doing a "machine video cga" then the screen is fine.

What version of DOS are you using --- I can't get machine mode cga
to do anything but tell me that cga isn't a valid option.  DOS 3.3+
and DOS 4.01 both do this on all the Z386/Z-549 machines I've tried
here.  If you can be a little more specific I'll take a look and see
if I can find out anything.

Oops, call it operator head space.  I meant MACHINE VIDEO CGA rather than
"machine mode cga".

If you can test this on your Z-386-33's with Z-549 video boards I would
appreciate it.  If it works if you could check which video board it really
it, ie. Western digital/Paradise for Zenith, or Zenith.

A long time ago I subscribed to Sextant, a magazine which specialized in 
the Heath/Zenith market.  The magazine used to have ads in it from 
various dealers sellings used and discontinued zenith systems, boards and
parts.  Sextant is no longer in business and I would like to find some 
dealers that still deal in zenith stuff.  

This request is prompted by the need to repair some old equipment we can't
afford to replace yet, and parts from dealers are just to expensive...
(a new motherboard for an XT laptop would run $384., to much to spend on
a system such as this).

Any help in locating sources of discontinued zenith systems, boards and
parts would be greatly appreciated.
